Air flow switch-differential Pressure Switch-HTW-AS-33Introduction:HTW-AS-33? differential pressure switches can sense the pressure difference , vacuum, over pressure, poor flow of the incorrosive gas.Conventional applications include :+ Monitoring Filters blocked Alarm Device+ Monitoring air blower running status.+ Monitoring air of ventilative pipelines?+ Controlling the largest gas flow of variable gas volume?+ Monitoring the gas of combustion furnace.


Product parameters:Measuring range: 20Pa~200PaMax.differential pressure: 12000PaDegree of protection: IP54Electrical rating value: <2A / 250VACWorking temperature:-15~+60Storage temperature: -40~85Min. actuating pressure: standard: 20Pa;min.starting----------------------------------- interval:10Pa(range: 20~30Pa)Linearity: range 50~500Pa <±3PaInstallation direction: vertical(standard installation style)Hose connection: pipeΦ6.2mmWeight: 100 grams without bracketRepeatability: <±0.025mbarIn the ranges 0.2 to 2mbar?Installation:Location: select a location where vibrations are minimal .Ambient temperature should be within the range of -15 / +60.The production calibration of the SA101 is made at room temperature ; mounting locations close to room temperatures are preferred . In systems with high humidity where condensation is possible, thus the entrance should point downwards.Pressure connection and wiring:Pressure connections are marked with P1⊕&P2Θ,incorrect connections are forbidden.Mounting instruction:The switch is preferably mounted with the diaphragm in a vertical plane , unless the device is set or calibrated for horizontal mounting as on special customer models. On these models the mountingposition is indicated on the side of the control .It m
